Eat plenty of fresh dark green leafy vegetables:Studies have shown that a diet rich in dark leafy greens helps support eye health, and those with the highest consumption of carotenoid-rich vegetables, especially ones rich in lutein and zeaxanthin, had increased vision health.

Avoid trans fats: A diet high in trans fat appears to contribute to macular degeneration by interfering with omega-3 fats in your body. Trans fat is found in many processed foods and baked goods, including margarine, shortening, fried foods like French fries, fried chicken and doughnuts, cookies, pastries and crackers.

Avoid aspartame:Vision problems are one of the many potential acute symptoms of aspartame poisoning.

Quit smoking: Smoking increases free radical production throughout your body, and puts you at risk for less-than-optimal health in many ways, including the risk of decreased vision.
